16 www.danahermotion.com Thomson Linear Motion Components The RoundRail Advantage… Die Set Ball Bushing Bearings Available in two accuracy classes and suitable for a variety of industrial applications. Thomson Die Set Ball Bushing Bearings are designed to fit the mounting holes of the punch holder in standard dies. When replacing high friction plain Bearings in standard dies, the result is less machine downtime and increased efficiency. With steady state speeds up to 10 ft/s, the Die Set bearing will provide faster cycle times, with improvements in production rates realized immediately. Matched precision ground 60 Case LinearRace allows for a close fit-up between the shaft and the LinearRace shafting and bearing providing critical die alignment. When normal machine service requires bearing replacement, the Die Set bearing can be removed by simply unbolting the toe clamps. Available in 1, 1 14, 1 1/2 and 2 inch sizes from over 1800 distributors worldwide. (See Page 79) XR Ball Bushing Bearing Products High load capacity and rigidity combined with the RoundRail Advantage. The XR Ball Bushing bearing provides five times the load capacity or 125 times the life of conventional linear Bearings. This increase in bearing performance significantly reduces downtime and maintenance, while increasing machine reliability. When replacing v-ways and flat-ways, XR Ball Bushing Bearings allow travel speeds up to 5 ft/s and accelerations up to 225 ft/s2 without a sharp increase in power consumption. XR Ball Bushing Bearings also provide three times the rigidity of conventional Ball Bushing Bearings reducing deflection in critical machining applications. Pillow Blocks are available with factory installed XR Ball Bushing Bearings and integral seals. 60 Case LinearRace shafting available premounted on standard extra rigid LinearRace support rails. Available in 2, 3 and 4 inch sizes from over 1800 distributors worldwide. (See Page 87) RoundWay Linear Roller Bearings Low friction roller Bearings with up to 20 times the load capacity of conventional linear Bearings. These patented, self-aligning linear roller Bearings have over 20 times the load capacity of a conventional linear ball bearing. This dramatic increase in bearing load capacity allows designers to optimize system compactness and minimize hardware costs. Combining the self-aligning feature with the RoundRail Advantage minimizes installation time and assures trouble-free operation. RoundWay and RoundWay II Bearings can achieve operating speeds up to 10 ft/s without the derating factors commonly seen with linear guides. When normal machine maintenance is required, RoundWay Bearings can be quickly and cost-effectively replaced, without scrapping the entire system, a major problem when servicing some linear guides. RoundWay Bearings are available from over 1800 authorized distributors worldwide. (See Page 94) Ball Bushing Bearings Overview
